Lifecycle Timeline
4DescriptionCVE.org
Adobe Experience Manager versions 6.5.24, FP11.7 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this issue by manipulating the DOM environment to execute malicious JavaScript within the context of the victim's browser. Exploitation of this issue requires user interaction in that a victim must visit a specially crafted web page.
AnalysisAI
DOM-based Cross-Site Scripting in Adobe Experience Manager 6.5.24 and FP11.7 and earlier allows authenticated attackers to execute arbitrary JavaScript in victims' browsers by crafting malicious web pages that manipulate the DOM environment, requiring user interaction to trigger the attack. CVSS 5.4 reflects moderate severity with network-accessible attack surface but limited scope impact. No public exploit code or active exploitation has been confirmed at time of analysis.
Technical ContextAI
This vulnerability exploits improper input sanitization in Adobe Experience Manager's DOM handling, falling under CWE-79 (Improper Neutralization of Input During Web Page Generation). DOM-based XSS occurs when untrusted user input is processed on the client-side and used to construct dynamic HTML without proper encoding or validation. The affected versions (6.5.24, FP11.7 and earlier) fail to adequately neutralize attacker-controlled data before it is rendered into the DOM, allowing malicious JavaScript injection. The CVSS vector indicates the vulnerability requires authenticated access (PR:L) and user interaction (UI:R), limiting the attack surface to authenticated users who can be socially engineered to visit a crafted page.
RemediationAI
Apply Adobe's patched release for Experience Manager versions addressing CVE-2026-34623 as documented in the official security advisory (https://helpx.adobe.com/security/products/aem-screens/apsb26-34.html). Upgrade all affected instances (6.5.24, FP11.7 and earlier) to the patched versions specified in Adobe's bulletin. As an interim control, restrict access to Adobe Experience Manager administrative interfaces to trusted networks and educate users about avoiding suspicious links or web pages that could trigger DOM-based XSS, though user-facing mitigations are not a substitute for patching. Verify DOM input sanitization in custom extensions and validate Content Security Policy (CSP) headers are properly configured to limit inline script execution.
